Advancing semantic data and AI infrastructure.
Fluree Labs explores knowledge graphs, immutable data, and trustworthy AI — shaping how the world structures and reasons about information.
Benchmark Studies

Large language models are powerful, but they hallucinate, lack provenance, and struggle with structured reasoning. Knowledge graphs provide the missing semantic layer that grounds AI in verifiable facts.
Immutable Data Architectures for Enterprise Trust
Why append-only, immutable data architectures are essential for building trustworthy enterprise systems — from audit trails to regulatory compliance.
FlureeQL vs SPARQL: Choosing the Right Query Language
A practical comparison of FlureeQL and SPARQL for querying semantic data — when to use each, syntax differences, and performance considerations.
Building a Semantic Data Layer for RAG Pipelines
How to build a semantic data layer that improves RAG pipeline accuracy by providing structured context, relationship awareness, and provenance tracking.
